6 Part Harken Ratcheted Block Tackle

The Harken 6 part ratcheted block tackle (4 metre drop) with Kong Tango locking gate carabiners at £595 plus £12.50 delivery to the UK is only available from us.

For International deliveries – which include deliveries to Northern Ireland – please contact us. The Harken 6 part ratcheted block is suitable for both sailing boats and motorboats

Worth noting;

– Other 6 part tackles whether ratcheted block or not will have a cam-cleat on the top block. You do not want a cam-cleat on the top block for MOB retrieval. You do not need a cam-cleat when the top block is ratcheted, and you certainly don’t want the hauling line locked off by a cam-cleat 15 feet up in the air while you need to lower the man to free him from the guard wire which has caught on his lifejacket. With the ratcheted block, the rescuer is easily able to hold the casualty’s weight on the hauling line between finger and thumb, which allows them to tie the hauling line off to the guard rail if they want a rest.

– Our Harken tackle comes with Kong Tango locking gate carabiners on either end, which are perfect for whacking at what you want to attach them to and which cannot open accidentally – unlike snap shackles which can open just when you do not want them to.

– Our tackle comes with a silk at either end to tie round the falls by the block to stop the block inverting and thus tangling. We recommend stowing the tackle fully extended, coiled into a bucket, ready to deploy. Other tackles may have velcro wraps for this but you need two hands to undo velcro. We attach our silks with a turn round the falls and then into a bow. You can undo a bow with one hand. Remember our MOB retrieval set up is designed for just one person to manage – the person perhaps who is left alone on the boat.

– Most important of all, the tackle that Harken make for us has been tested for lifting people. These tests are much more stringent than the tests that blocks will undergo, for a mainsheet system for example. Our Harken tackle has been tested to the breaking strain of its weakest component. The break load is 1700Kg – this is then divided by 10 to give a Safe Working Load of 170Kg. A safe working load is a load that rates something for daily use. With our Harken tackle we hope never to use it at all, never mind daily.

So, if you see a tackle and MOB retrieval set up advertised for man overboard recovery and it has not been tested and rated to these stringent standards then it is not for man overboard recovery and shouldn’t be advertised as such.

Our Harken retrieval kit is rated for man overboard recovery – and you can’t get it anywhere else in the world.

And as such it needs to be kept for man overboard retrieval and not be used for general lifting about the boat. It also needs to be stowed correctly. That is down below in a cabin, not in a damp cockpit locker or set up permanently on a mast or back rail. Why? Because u/v rays from the sun will cause photodegradation where the ultra violet breaks down the molecular structure of the rope.

KONG CARABINER

Kong Carabiners are anodised aluminium. The anodising helps to prevent corrosion in the marine environment. Rated to 3.3 tons – should do the job, even for me! The gate locks until you press the back. When you whack the carabiner at what you want to attach it to your hand naturally presses on the back and so releases the gate. Kong Carabiners are ideal for whacking onto the handle of the MOB Lifesaver. Notice that the shackle attach the Kong to the Harken block has been moused with wire. You wouldn’t want the pin to fly out mid MOB retrieval. Now it’s moused it certainly won’t.
